Exactly a point that I made too.

>From the moment that we introduced the notion of an "active"
region (i.e. introduced `transient-mark-mode') the fact that a
region is active means, in effect, that you expect to (because
you are able to) do something with it.

That's not necessarily the case for all uses of `C-x C-x'. When
it's not the case, you can use `C-g' to deactivate it. And that's
what you would (have to) do if `d-s-m' is enabled and you do
not want to act on it (e.g. delete/replace it).

If the annoyance for `d-s-m' for a particular user comes only
from `C-x C-x' then a solution (for that user) is to have an
equivalent of `C-x C-x' that does not activate (or that then
deactivates) the region.
